Answer:
A.) k=0.5
Step-by-step explanation:
If we use the formula given: y=kx, we can plug in values.
0.5=k(1)
0.5=(0.5)(1)
0.5=0.5
We know that to get from 1 to 0.5, we need to divide by two, or multiple by 1/2. 1/2 in decimal form is 0.5
 
        
             
        
        
        
7x-35<2x-10 distribut it
7x-2x<-10+35 collect like them 
5x<25 divide both side by 5
x<5
